Patent JP-S5698058-A (JP)
Title: Channel control system
Inventor: SAKATA TAKAO
IPC: H04L29/10
Filed: 1979-12-30
Abstract: PURPOSE:To ensure an automatic switching of the transmission mode even in such an abnormal state in which the one-way transmission signal is recovered from the step-out of synchronism, by transmitting the channel control signal by the hand shaking. CONSTITUTION:The transmission data supplied from the terminal via the interface part 1 receives a start-stop reproduction at the transmission start-stop reproduction part 2 to be supplied to the switch 4. At the same time, the input/output channel control signal is supplied to the switch 4 after receiving a parallel-serial conversion at the transmission control signal generating part 3. The transmission mode deciding part 5 monitors the channel control signal and the reception control signal of the reception control signal converting part 9 to decide the transmission mode, and controls the switch 4. Thus the data signal and the control signal are transmitted in the data transmission mode and the control mode respectively. On the other hand, the output channel delivered to the part 3 is sent back via the switch 4 to be compared with the control signal transmitted at the part 5. When a coincidence is obtained there, the synchronism is decided to perform a switching to the transmission mode. While in case no coincidence is obtained, the control mode is held until a coincidence is obtained.

Title: Latent image stabilizing method
Inventor: KONAKA TOSHIO
IPC: G03G15/00
Filed: 1979-12-30
Abstract: PURPOSE: To stabilize deepness of a latent image and to enhance image quality, by controlling a driver for forming a latent image by output of a comparator.  
     CONSTITUTION: Surface potential due to uniform charging of photoconductive layer 1 is measured with first potential measuring sensor 14, and area occupied by an image is obtained by adding with adder 18 the dot number of a dot pattern produced with character generating device 15. Drop ratio of the surface potential is  computed from this image area. The mean surface potential of layer 1 after formation of a latent image is measured with second potential measuring sensor 21, and  the measured mean surface potential is divided by the drop ratio of the surface  potential with divider 20. The output of sensor 14 are compared with that of divider 20 by means of comparator 22, and driver 16 for forming the latent image is  controlled with the output of this comparator 22, thus permitting deepness of the  latent image to be stabilized.

Filed: 1987-07-10
Abstract: PURPOSE: To prolong the lifetime of a fan motor while enhancing operational economy thereof by controlling the cooling capacity and stopping the fan motor when the cooling capacity becomes lower than a specified level. CONSTITUTION: A controller CNT 6 has a function for determining the output frequency of an inverter INV 5 depending on a command being delivered thereto.
